Suggestion to add an option to automatically leave inactive group chats.

So, I've been using discord for a really long time. I'm probably not the only one that keeps making new group chats and inviting new friends, and if you do you probably also find it really annoying having to go through and leave all of them. So my suggestion is to add a tool that automatically leaves group chats that have been inactive for a certain amount of time, for example, 1 week, 2 weeks and so on. 

Maybe you can add a "clear" button which will close dm's and leaves groups that are inactive
